Dielectric Coated Off-axis Mirrors

Specialists in high precision optics Optical Surfaces Ltd produces extremely durable coated mirrors up to 600 mm in diameter for use with high-power femtosecond lasers in applications that include plasma physics, laser manufacturing, and telecommunications.

Using proprietary manufacturing techniques and the latest dielectric coating technology Optical Surfaces Ltd is able to produce off-axis paraboloids, which optimise the performance of rapid-pulsed lasers, from materials including glass, ceramic, and silica. The mirrors provide minimum pulse distortion and the maximum usable bandwidth. When used with high-power femtosecond lasers operating at 750 to 850 nm, typically Optical Surfaces produces mirrors that accommodate power densities up to 100 mJ/cm2 for continuous 50-fs pulses.
